If a value is expected to be in a particular register for a register
merge, allow for it to be moved there from another register, without
expecting it to be spilled.

In addition to the marking barrier we now also need the shared barrier
for properly tracking the old-to-shared remembered set. So invoke
the full write barrier for set_map and set_map_after_allocation.

Currently, we canonicalize types for call_indirect by looking in the
current module for a signature of the same shape. This is not enough
as of wasm-gc. Instead, the canonical identifier representing a type
has to be computed via isorecursive canonicalization.
This change is implemented behind a flag for now.
Future work: Also integrate export wrappers with isorecursive
canonical types. We need to store wrappers in instance-independent
storage.

Drive-by:
- Always emit type check for call_indirect. We did not emit a check
  only when typed-function-references was enabled, but not gc. This
  is not something that will be possible long-term.
- Fix some wasm cctests.

CreateJob() doesn't schedule anything until Join() or Notify*() is called. CreateJob().Join() will thus schedule the right number of
workers for the job right away (taking into account the main thread
contributes), whereas PostJob().Join() schedules 1 worker that won't
be necessary once doing Join() and the main thread kicks in.
This has the effect of reducing 1 unnecessary context switch each time
the jobs are schedule.

The unit test has been updated to work correctly when
--stress-incremental-marking is enabled.

Original change's description:
> Background merging of deserialized scripts
>
> Recently, https://crrev.com/c/v8/v8/+/3681880 added new API functions
> with which an embedder could request that V8 merge newly deserialized
> script data into an existing Script from the Isolate's compilation
> cache. This change implements those new functions. This functionality is
> still disabled by default due to the flag
> merge_background_deserialized_script_with_compilation_cache.
>
> The goal of this new functionality is to reduce memory usage when
> multiple frames load the same script with a long delay between (long
> enough for the script to have been evicted from Blink's in-memory cache
> and for the top-level SharedFunctionInfo to be flushed). In that case,
> there are two Script objects for the same script: one which was found in
> the Isolate compilation cache (the "old" script), and one which was
> recently deserialized (the "new" script). The new script's object graph
> is essentially standalone: it may point to internalized strings and
> readonly objects such as the empty feedback metadata, but otherwise
> it is unconnected to the rest of the heap. The merging logic takes any
> useful data from the new script's object graph and attaches it into the
> old script's object graph, so that the new Script object and any other
> duplicated objects can be discarded. More specifically:
>
> 1. If the new Script has a SharedFunctionInfo for a particular function
>    literal, and the old Script does not, then the old Script is updated
>    to refer to the new SharedFunctionInfo.
> 2. If the new Script has a compiled SharedFunctionInfo for a particular
>    function literal, and the old Script has an uncompiled
>    SharedFunctionInfo, then the old SharedFunctionInfo is updated to
>    point to the function_data and feedback_metadata from the new
>    SharedFunctionInfo.
> 3. If any used object from the new object graph points to a
>    SharedFunctionInfo, where the old object graph contains a matching
>    SharedFunctionInfo for the same function literal, then that pointer
>    is updated to point to the old SharedFunctionInfo.
>
> The document at [0] includes diagrams showing an example merge on a very
> small script.
>
> Steps 1 and 2 above are pretty simple, but step 3 requires walking a
> possibly large set of objects, so this new API lets the embedder run
> step 3 from a background thread. Steps 1 and 2 are performed later, on
> the main thread.
>
> The next important question is: in what ways can the old script's object
> graph be modified during the background execution of step 3, or during
> the time after step 3 but before steps 1 and 2?
>
> A. SharedFunctionInfos can go from compiled to uncompiled due to
>    flushing. This is okay; the worst outcome is that the function would
>    need to be compiled again later. Such a risk is already present,
>    since V8 doesn't keep IsCompiledScopes for every compiled function in
>    a background-deserialized script.
> B. SharedFunctionInfos can go from uncompiled to compiled due to lazy
>    compilation. This is also okay; the merge completion logic on the
>    main thread will just keep this lazily compiled data rather than
>    inserting compiled data from the newly deserialized object graph.
> C. SharedFunctionInfos can be cleared from the Script's weak array if
>    they are no longer referenced. This is mostly okay, because any
>    SharedFunctionInfo that is needed by the background merge is strongly
>    referenced and therefore can't be cleared. The only problem arises if
>    the top-level SharedFunctionInfo gets cleared, so the merge task must
>    deliberately keep a reference to that one.
> D. SharedFunctionInfos can be created if they are needed due to lazy
>    compilation of a parent function. This change is somewhat troublesome
>    because it invalidates the background thread's work and requires a
>    re-traversal on the main thread to update any pointers that should
>    point to this lazily compiled SharedFunctionInfo.
>
> At a high level, this change implements three previously unimplemented
> functions in BackgroundDeserializeTask (in compiler.cc) and updates one:
>
> - BackgroundDeserializeTask::SourceTextAvailable, run on the main
>   thread, checks whether there is a matching Script in the Isolate
>   compilation cache which doesn't already have a top-level
>   SharedFunctionInfo. If so, it saves that Script in a persistent
>   handle.
> - BackgroundDeserializeTask::ShouldMergeWithExistingScript checks
>   whether the persistent handle from the first step exists (a fast
>   operation which can be called from any thread).
> - BackgroundDeserializeTask::MergeWithExistingScript, run on a
>   background thread, performs step 3 of the merge described above and
>   generates lists of persistent data describing how the main thread can
>   complete the merge.
> - BackgroundDeserializeTask::Finish is updated to perform the merge
>   steps 1 and 2 listed above, as well as a possible re-traversal of the
>   graph if required due to newly created SharedFunctionInfos in the old
>   Script.
>
> The merge logic has nothing to do with deserialization, and indeed I
> hope to reuse it for background compilation tasks as well, so it is all
> contained within a new class BackgroundMergeTask (in compiler.h,cc). It
> uses a second class, ForwardPointersVisitor (in compiler.cc) to perform
> the object visitation that updates pointers to SharedFunctionInfos.

Memory64 currently does not use trap handling, so we should not allocate
a guard region (10GB total reservation).
This is implemented by adding a {WasmMemoryFlag} enum in the backing
store header, which replaces the previous {MemoryIndexType}. The flag is
not stored with the backing store, as the backing store does not care
about the index type, and we might want to share the same backing store
for memory32 and memory64 (if sizes permit this).
Instead, we (still) store the flag with the WasmMemoryObject and pass it
to the backing store methods.

Register merges participate in the same parallel gap move as phi inputs,
but their allocation is not aware of the phis' existence (since the
register merge allocation sees the register state _before_ phi input
allocation, which is because that's what parallel move requires). This
means that they might move into a register that is used by a Phi, and
possibly will clobber its value.

Avoid this by recording what registers phis move values into during code
gen, and skipping register moves into those registers. Also DCHECK that
the recorded gap moves can't clobber a target register from a previous
gap move. Additionally, add printing for register merges (both in
regalloc tracing and graph printing).
